Overview
org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Missing Authorization in the admin REST API through the deleteComposites role-composite deletion path in RoleResource, RoleContainerResource, and RoleByIdResource. An attacker with limited administrative permissions can remove privileged child roles from a composite role by sending DELETE requests to the role composite endpoints. The vulnerable endpoints only checked manage permission on the parent role and did not enforce per-child role authorization before role.removeCompositeRole(composite). As a result, a delegated administrator can strip roles they are not authorized to map, breaking role assignments for other users and administrators and causing access loss.
